IEC 62938 ed.012020-05 Photovoltaic (PV)modules-Non-uniform snow load testing

■ Equipment functions：When the component is installed outdoors, it is installed at a 37 ° angle to the ground. When encountering heavy snow weather, the surface of the component will accumulate thick snow. Due to the inclined installation of the component at a certain angle to the ground, the surface with the lowest inclination angle carries the maximum pressure, and the pressure on the component surface decreases upward with the inclination angle of the component; The test component is installed on an adjustable angle mounting surface, and there is a weight hanging platform at a certain distance parallel to the component mounting surface. The weights can be neatly stacked on the component surface, and the weight of the weights decreases upwards at the inclination angle of the component to achieve the effect of uneven load.
